A group of Boulder residents is organizing a "silent" walk on the Pearl Street Mall on Sunday to honor the elk shot in the Mapleton Hill neighborhood on New Year's Day.

The announcement on the Facebook page said participants will be silent during the walk except for the playing of a recording of an elk bugle from their phones.

According to the page, the purpose of the walk is to "continue to raise awareness of the 'Justice for Mapleton Elk's' cause and to keep the issue in the forefront. We are concerned the investigation will drag its feet. We will not."

The "Justice for the Mapleton Elk" page also is distributing a poster that shows a photo of an elk with the inscription "No hunting in our 'hood," and is asking Boulder residents to display the signs on their properties and along the Pearl Street Mall.

On Thursday, Boulder County District Attorney Stan Garnett said no decision on charges against the two Boulder police officers involved in the shooting -- Sam Carter and Brent Curnow -- will be made this week.

According to police, an on-duty Boulder police officer spotted an injured elk near Ninth Street and Mapleton Avenue late on Jan. 1 and determined it needed to be euthanized. The officer killed the elk with a shotgun, then called an off-duty police officer to come and pick up the carcass.

The officer did not report the incident to dispatchers or supervisors.

Both Carter and Curnow have been placed on paid leave while a criminal investigation is completed by Colorado Parks and Wildlife. Boulder police also are conducting an internal personnel investigation.

Boulder County sheriff's Deputy Jeff George also is the subject of an internal investigation by his department for his role in the incident. Sheriff's officials say he helped load the elk into a truck that night.
